The first of two essays in this issue demonstrated that the United States has had a rich history of medical pluralism. This essay seeks to present an overview of contemporary unconventional medical practices in the United States. No clear definition of "alternative medicine" is offered because it is a residual category composed of heterogeneous healing methods. A descriptive taxonomy of contemp...

stabilization, alter and improvement of engineering properties of soil are for providing predetermined goals. the most important aim of soil stabilization is increasing long term soil strength, but in very wet and loos lands the other aim of soil stabilization, is to decrease plasticity characteristic of soil, which are tested by atterberg limits tests. since the road soils of namkhane district...

background: the rodent somatosensory barrel cortex is an ideal model to examine the effect of experience-dependent plasticity on developing brain circuitry. sensory deprivation such as whisker deprivation may affect neuroanatomical aspects of the brain during developmental processes. the present study designed to investigate the possible effects of whisker deprivation on the morphometric charac...

long-term potentiation (ltp) is a reflection of synaptic plasticity that induced by specific patterns of synaptic activity and has an important role in learning and memory. the first clue of the potential role of glutamate receptors in ltp was in 1991 with the observation that the mglur agonists 1-amino-1, 3-cyclopentanedicarboxylic acid (acpd), increased ltp. studies have shown that acpd induc...

Long-term potentiation (LTP) is a form of activity-dependent plasticity that occurs during learning. Potassium channels are the most diverse group of all ion channels that related to synaptic plasticity. Small-conductance calcium-activated potassium channels (SKs) are found in hippocampal CA1 neurons and by inhibiting of postsynaptic potentials are involved in synaptic transmission impairment. ...

Recently many people discuss unconventional density waves (i.e. unconventional charge density waves (UCDW) and unconventional spin density waves (USDW)). Unlike in conventional density waves, the quasiparticle spectrum in these systems is gapless. Also these systems remain metallic. Indeed it appears that there are many candidates for UDW. The low temperature phase of α-(BEDT-TTF)2KHg(SCN)4, th...

Unconventional hydrocarbon resources from low-permeability formation, i.e., tight sands and shales, are currently received great attention because of their potential to supply the entire world with sufficient energy for the decades to come. In the past few years, as a result of industry-wide R&D effort, progresses are being made towards commercial development of gas and oil from such unconventi...

introduction: neuro-plasticity is the neuronal system ability to modify and recover itself after the occurrence of impairment and injuries. following the abolition of a sensory modality, modifications will be applied to other modalities and their cortical function in a way that the processing of these modalities not only will happen in their own specific cortical area, but also in those areas t...

We examine the effects of unconventional monetary policy surprises on the value of the dollar using high-frequency intraday data and contrast them with the effects of conventional policy tools. Identifying monetary policy surprises from changes in interest rate future prices in narrow windows around policy announcements, we find that monetary policy surprises since the Federal Reserve lowered i...

Background and purpose: Glial cells seem to play role in synaptic plasticity because they have the ability to release trophic factors and gliotransmitters and respond to neurotransmitters. They also play important role in synaptic space homeostasis. In this study, the role of hippocampal glial cells in baseline synaptic response and short term synaptic plasticity were investigated.  Material...
